Hello again,
With the help of Wikimédia France and Reda Kerbouche [1], I reached some external experts to confirm the validity of the Tacawit (also called
Shawiya in English and chaoui in French) Wiktionary [2], and they confirmed that the language is the correct one. They also confirmed that the Latin alphabet, which the Wiktionary is written in, is the most used for spelling this language, so
it is the main one that should be used for Wikimedia projects.
The localisation requirements are met [3] and there is steady activity in the Incubator [4], so I would like to formally suggest approval of this Wiktionary. One interesting fact is that this would be the first language in Wikimedia projects where a Wikipedia
would not be the first project created for the language, so it is a milestone of sorts.
[1] Reda is one of the main contributors to the Tacawit Wiktionary, but also a well-known and well-respected Wikimedian in other projects – I'm sure some of you already know him.
